Head lamp



Aug. 6, 1935. H. c. FOLKERTH HEAD LAMP Filed Aug. 6, 1934 Inventor Early C. fzzlerfk Q By flllorney Patented Aug. 6, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a headlamp, the general object of the invention being to provide means whereby the road is properly illuminated without blinding drivers of approaching vehicles,

with means for providing a parking light in the upper portion of the lamp and means associated therewith for enabling signs and the like to be read.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is a front view of the improved headlamp with the transparent member broken away.

Fig. 2 is a longitudinal sectional view of the improved lamp.

In this drawing, the numeral l indicates the lamp case which has the usual transparent memher 2 in its front end and a horizontally arranged barrel 3 is supported intermediate the ends of the casing by the'brackets 4. A double condensing lens 5 is carried by the barrel and the socket 6 for the bulb l is supported by the bracket 8 in such a manner that the bulb is centrally arranged in rear of the lens. A bracket 9 of angle shape is connected with the socket member and has a hole in its upper end in which a screw it passes, the screw passing through a hole in the rear end of the casing so that it can be adjusted from the exterior part of the casing. A spring H is placed between the bracket 9 and the rear end of the casing for holding the parts from detachment.

A metal member A is placed in the front of the casing between the transparent member 2 and the front end of the barrel 3 and has the front lower portion of substantially semicircular form as shown at [2 with the rear part sloping upwardly and rearwardly in the barrel as shown at I3 and a downwardly and forwardly sloping partition member I4 extends across the top of the member A and has its rear face polished o1 reflective while its upper face is dull or dark. This member I4 will reflect the rays of light passing through the lens 5 downwardly and rearwardly and the part l3 will reflect such rays forwardly through the transparent member and upon the road. A small lamp bulb I5 is placed in the upper part of the member A above the member l4 and a curved reflector 16 extends forwardly under this bulb and acts to reflect the light therefrom upwardly through the transparent member to illuminate road signs and the like. I prefer to make this bulb I5 in such a manner that it can either give a dim light or a bright light, the bright light being used when a sign is to be read and the dim light to be used when the bulb is to be used for parking purposes.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

, I claim:

A headlamp of the class described comprising a casing, means for supporting a bulb in the rear part thereof, a double condensing lens supported in the casing in front of the bulb, a downwardly and forwardly sloping member in the front part of the casing having its under face polished and its upper face dark, the under face reflecting the rays of light downwardly and rearwardly, a reflector member in the lower front part of the casing to reflect the rays of light from the first refleeting member forwardly, a small bulb in the upper front portion of the casing and a reflector for reflecting the light rays upwardly and forwardly therefrom.
